HECEPTACLE AND SNAP-0N COVER THEREFOR Filed NOV. 21, 1941 zlwuen vm Ra/p/ V B 61 Patented Mar. 16, 1943 umren sra'rr s rare RECEPTACLE AND SNAP-ON COVER THEREFOR Ralph V. Burdick, Albany, N. Y. Application November 21, 1941, Serial No. 420,024

1 Claim. (.01. 220-430) The present invention relates generally to receptacles and more particularly to a novel construction of means for associating the covers therewith to maintain a predetermined tightness of fit, and also facilitate the removal of the covers when desired.

One of the chief characteristics of the present invention resides in the provision of a receptacle and cover therefor of novel construction, whereby the cover is effectively sealed against the upper edge of the receptacle with a predetermined degree of pressure, incident to its initial application thereto, and the tightness of fit constantly maintained under all conditions, as the cover can not become partially loosened thereon, which would of course destroy the seal.

In carrying out the invention, I comprehend a novel construction of means whereby the cover is adapted to be snapped on the receptacle in a manner to insure and maintain a constant predetermined pressure seal against the edge of the receptacle, and at the same time permit the cover to be easily and quickly released from the receptacle for removal incident to a partial rotation of the cover in either direction.

The nature and advantages of the invention will be more fully understood from the following detail description when read in connection with the accompanying drawing, the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawing forming part of this application like numerals of reference indicate similar parts in the several views and wherein:

Figure 1 is a transverse sectional view.

Figure 2 is a perspective view of the cover for the receptacle.

Figure 3 is a perspective view of the receptacle.

Figure 4 is a sectional view showing the cover released.

Figure 5 is a fragmentary side elevation partly broken away.

Before entering into a detail description of what is herein shown, I desire to have it understood that a general application or use of the invention with any and all types of receptacles is contemplated by the claim.

Referring to the drawing in detail ltl indicates the body of the receptacle which may of course be constructed of any suitable material and vary in size without departing from the spirit of the invention. The body of the receptacle and its cover are provided with cooperating means for effectively maintaining the latter sealed with a predetermined degree of pressure, and this means is brought into use incident to the initial application of the cover to the receptacle. In other words, the cover is adapted to be snapped on the receptacle, and this can be accomplished with a minimum of effort. When the cover is snapped on the receptacle, the tightness of fit is constantly maintained under all conditions, as the cover can not become partially loosened thereon, which would of course destroy the seal.

In accordance with the instant invention, the body of the receptacle is provided with an annular groove l I located adjacent the upper edge of the receptacle, and spaced a predetermined distance therefrom. The body Iii of the receptacle is also provided with an external segmental bead l3 which may of course vary in length, and is located directly beneath the groove ll. Both the groove ll andithe head [3 reinforces the Wall of the receptacle, so that it is not necessary to provide the same with the usual corrugations or the like.

The cover is indicated at I4 and is preferably provided with the usual sealing disk or liner E5. The flange of the cover is provided with means to cooperate with the groove II of the receptacle and the bead E3 to effectively seal the cover against the upper edge of the receptacle when the cover is snapped on the latter, and at the same time permit the cover to be quickly released incident to a partial rotation thereof in either direction. The means for this purpose preferably includes a pair of internal segmental heads I 5 and il respectively. While these beads may vary in length, they are diametrically opposed and lie in relatively different planes. Upon reference to the drawing it will be noted that the internal segmental bead I6 is arranged on the flange of the cover in close proximity to the top thereof, while the internal segmental bead I! is carried by sa d flange immediately adjacent the lower edge thereof. The respective internal beads are of substantially the same length, and manifestly serve to reinforce the cover so as to make the use of corrugations or the like unnecessary. By virtue of the relative disposition of the respective internal beads l6 and Il, it is obvious that when the cover is snapped on the receptacle, the upper bead i6 is received by the groove II, while the lower bead ll snaps over and engages the underside of the external bead l3 carried by the receptacle. Consequently, these cooperating characteristic features of the construction serve to effectively seal the cover against the upper edge of the receptacle with a predetermined degree of pressure, and the tightness of fit constantly
